Abstract:
Plasma from Earth’s magnetotail is transported Earthward during storms and substorms, driving the dynamics in the inner magnetosphere. Rather than continuous flow across the entire magnetotail, it has been found that the particles are transported in a localized, bursty way. The particles appear to be transported in narrow flow channels of ~1-2 RE, as shown in MHD simulations. The details of magnetotail particle dynamics from the reconnection region to injection in the inner magnetosphere are critical to understanding storms and substorms. We demonstrate that narrow regions of increased ion temperatures indicative of these flow channels are observed in energetic neutral atom (ENA) images from the TWINS mission and present results with coordinated in situ measurements and MHD simulations.
